The 68 axke u clanp bolts from Roskauto fitted right in to my mono leaf spring 10 bolt chevy setup I know have the spring perches welded and with 4 axle u clamp bolts all I had to do was cut off 2" of excess thread.

I am now waiting on my fuel tank which is stuck in UK customs for a week so far! That sucks but if it arrives in time drag racing next weekend.
